Poll indicates Clinton would do better against McCain

It's likely too little, too late to make a difference, but a new national poll out today suggests that Hillary Clinton would fare better against Republican John McCain than likely Democratic nominee Barack Obama.

The USA Today/Gallup survey published today says Obama has an edge over McCain of 47 percent to 44 percent among registered voters, though that difference is within the poll's margin of error of plus or minus 4 percentage points. A month ago, McCain led 47 percent to 45 percent.

Clinton leads McCain 49 percent to 43 percent in the survey, conducted Friday through Sunday. She and her campaign have been making the electability argument that she would be the stronger Democratic nominee to the dwindling number of undeclared superdelegates who could stave off her elimination from the race.

The poll found no groundswell among Democrats for Clinton to quit the race: 59 percent say she should continue to campaign. And in what might reflect sympathy as she winds down her presidential bid, her favorability marks among all voters -- 54 percent favorable, 43 percent unfavorable -- are higher than in more than a year. Both Obama, at 58 percent, and McCain, at 56 percent, still have higher favorability numbers.
